The supplier denied including PPA, yet declined to reveal what had been included in the binder. When pushed by the division of transport, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB consists of a little amount of phosphorus, which is what department drug stores initially recognized.


"No person knew this material was being included in asphalt, had actually seen any kind of study on how this may impact efficiency of hot-mix asphalt pavements, or knew for the length of time and just how commonly it was being made use of throughout the country," claims Mueller.
